Windows 10 Pro Overview Windows 10 is a series of operating systems for personal computers produced by Microsoft as part of its Windows NT family of operating systems.
Windows 10 receives new versions regularly, which are available at no additional cost to users
Devices in enterprise environments may receive these updates at a slower pace or use long-term support milestones that receive only critical updates, such as security fixes, during their ten-year extended support lifespan.
One of the most notable features of Windows 10 is support for Universal Apps, an extension of the Metro-style apps first introduced in Windows 8
Universal apps can be designed to run across multiple families of Microsoft products with nearly identical code, including PCs, tablets, smartphones, embedded systems, Xbox One, Surface Hub, and Mixed Reality.
The Windows user interface has been overhauled to handle transitions between a mouse-oriented interface and a touch-optimized interface based on available input devices
Particularly on 2-in-1 PCs, both interfaces include an updated Start menu that integrates elements from the traditional Windows 7 Start menu with Windows 8 tiles.
